wheel bolt torque SKODA ROOMSTER 2013 1.G Owner's Manual

WARNINGObserve the following information regarding the wheel bolts.■The wheel bolts must be clean and must turn easily. Never apply grease or
oil.■
The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
■
If the wheel bolts are tightened to an insufficient tightening torque, the
rims may come loose when the car is moving – risk of accident! A tightening
torque which is too high can damage the bolts and threads and this can result
in permanent deformation of the contact surfaces on the rim.
■
If the wheel bolts are handled incorrectly, the wheel may come loose when
the car is moving – risk of accident!
WARNINGObserve the following information regarding the spare wheel.■Only use the spare wheel for as long as is necessary.■
Never drive with more than one spare wheel attached.
■
The snow chains cannot be used on the spare wheel.
CAUTION
■ If a spare wheel is used that is not identical to the fitted tyres, the following
must be observed » page 176, Spare wheel .■
Protect the tyres from contact with oil, grease and fuel.
■
Replace lost valve caps.
■
If, in the event of a puncture, it is necessary to fit a spare wheel with a tyre
without a dedicated running direction or with the opposite direction of rotation, drive carefully as the optimal characteristics of the tyre are no longer applicable in
this situation.
For the sake of the environment
Tyres that are insufficiently inflated increase your fuel consumption.
Note
■ We recommend that any work on the wheels or tyres be carried out by a spe-
cialist garage.■
We recommend that you use wheel rims, tyres, full wheel trims and snow chains
from ŠKODA Original Accessories.

Service life of tyresFig. 135
Principle sketch: Tyre tread with wear indicators/open fuel filler
flap with a table detailing the tyre sizes and tyre inflation pressures
Fig. 136
Replacing wheels
First read and observe the introductory information and safety warn-
ings on page 172.
The service life of tyres depends on the inflation pressure, driving style and other
circumstances. Following the advice below can extend the life cycle of your tyres.
Tyre pressure
Check the tyre pressure, including that of the spare wheel, at least once a month and also before setting off on a long journey.
The tyre pressures for tyres are shown on the inside of the fuel filler
flap » Fig. 135 –
.
The tyre pressure for the spare wheel should correspond to the highest pressure
specified for your vehicle. 

WARNINGObserve the following instructions for lifting the vehicle.■If the wheel has to be changed on a slope, first of all block the opposite
wheel with a stone or similar object to prevent the vehicle from unexpectedly
rolling away.■
Secure the base plate of the lifting jack with suitable means to prevent pos-
sible moving. A soft and slippery ground under the base plate may move the lifting jack, causing the vehicle to fall down. It is therefore always necessary to
place the lifting jack on a solid surface or use a wide and stable base. Use a non-slip base (e.g. a rubber foot mat) if the surface is smooth, such as cobbled
stones, tiled floor, etc.
■
Only attach the lifting jack to the attachment points provided for this pur-
pose.
■
Always raise the vehicle with the doors closed.
■
Never position any body parts, such as arms or legs under the vehicle, while
the vehicle is raised with a lifting jack.
■
Never start the engine when the vehicle is raised – risk of injury.
CAUTION
■ The tightening torque specified for the wheel bolts for steel and light alloy
wheels is 120 Nm.■
The anti-theft wheel bolt or the adapter can be damaged if the wheel bolts are
tightened too much.
Note
■ The anti-theft wheel bolt set and adapter can be purchased from a ŠKODA Part-
ner.■
The national legal requirements must be observed when changing a wheel.

Preliminary work
First read and observe the introductory information and safety warn-ings
on page 180.
Always change a wheel on a level surface as far as possible.
The following steps must be carried out before actually changing the wheel:
› Have
all the occupants get out. The passengers should not stand on the road
(instead they should remain behind a crash barrier, for instance) while the wheel is being changed.›
Switch off the engine.
›
Move the gearshift lever into Neutral or move the selector lever for the auto-
matic gearbox into position P.
›
Apply the handbrake firmly.
›
Uncouple a trailer.
›
Remove the vehicle tool kit » page 180 and the spare wheel » page 176 , Spare
wheel from the boot.

Changing a wheel
First read and observe the introductory information and safety warn-
ings
on page 180.
›
Remove the full wheel trim » page 177 or caps » page 177 .
›
In the case of light alloy wheel rims remove the wheel trim cap » page 177.
›
First of all slacken the anti-theft wheel bolt and then the other wheel
bolts » page 182 .
›
Jack up the vehicle until the wheel that needs changing is clear of the
ground » page 183 .
›
Unscrew the wheel bolts and place them on a clean surface (cloth, paper, etc.).
›
Remove the wheel carefully.
›
Attach the spare wheel and slightly screw on the wheel bolts.
›
Lower the vehicle.
›
Tighten the opposite wheel bolts alternately (cross-wise) with the wheel
wrench. Tighten the anti-theft wheel bolt last » page 182.
›
Reinstall the wheel trim/wheel trim cap or the caps.
Note
■
All bolts must be clean and must turn easily.■Under no circumstances grease or oil the wheel bolts!■
When fitting unidirectional tyres, ensure that the direction of rotation is cor-
rect » page 172 .

Follow-up workFirst read and observe the introductory information and safety warn-
ings
on page 180.
The following steps must also be performed after changing the wheel.
›
Stow and attach the replaced wheel in the spare wheel well using a special screw » page 176 , Spare wheel .
›
Stow the tool kit in the space provided and secure using the strap.
›
Check the tyre pressure on the installed spare wheel as soon as possible.
›
Have the tightening torque of the wheel bolts checked with a torque wrench
as soon as possible.
›
Replace the damaged wheel or consult a specialist garage about repair options.
Note
■ If it is determined that the wheel bolts are corroded and difficult to turn when
changing the wheel, the bolts must be replaced before checking the tightening
torque.■
Drive cautiously and only at a moderate speed until the tightening torque has
been checked.
